Outcomes
Primary outcome [1] 286535 0
Surgical site infection.
Using the standard follow-up tool to our department - the "Lead Maternit Carer" (LMC) reviews the patient regularily once discharged over the 6 weeks post-partum. Any surgical site infection is reported back at 6 weeks.
The surgical site infection is defines as:
Superficial and Deep Surgical Site Infection: Infection within 30 days of operation.
Superficial - involves skin/sub-cut tissue of incision only and one of; purulent discharge, organisms isolated from aseptically obtained culture, pain or tenderness, localised swelling, redness, heat, superficial incision opened by surgeon unless culture negative, diagnosis of infection by attending physician/surgeon.
Deep - involves deep soft tissue and one of; purulant discharge, spontaneous dehiscence or deliberately opened in the presence of temp >38C or pain/tenderness unless culture negative, abscess found on examination during surgery, radiology or histopathology, diagnosis of deep infection by attending physician/surgeon.
Timepoint [1] 286535 0
Wound infection within 30 days post-caesarean section reported back at 6 weeks post-partum by the LMC.
Secondary outcome [1] 296105 0
Wound/fascial dehiscence.
In event of suspected wound dehiscence the patient will be reviewed at Dunedin Hospital, Queen Mary Maternity Services and fascial dehiscence will be diagnosed by medical staff (independant medical examination).
Timepoint [1] 296105 0
Within 30 days post-caesarean section.

Eligibility
Key inclusion criteria
Elective, semi-elective and emergency caesarean sections in women seen and consented in an Antenatal Clinic or Antenatal Ward setting prior to presentation on the day of surgery. (E.g. including women undergoing emergency caesarean section during attempted vaginal birth after previous caesarean section if seen and consented in antenatal clinic on a prior occasion).
Minimum age
18 Years
Maximum age
45 Years
Sex
Females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Pre-existing Type 1 or 2 Diabetes (not Gestational diabetes which should resolve post-delivery and remove the increased risk of infection post-operatively).

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Information about the study will be passed to women either attending antenatal clinic or present on the antenatal ward and planned/high risk for a Caesarean section. Consent shall be taken if a woman agrees to enter the study and is not in labour.
Envelope method with variable block size – chosen to reduce any perceived complication of randomisation (especially in the case of Emergency Caesareans performed at night) and increase uptake.
Randomised by the circulating midwife, prepared by the scrub midwife and then blinded to the surgeon, woman undergoing caesarean and LMC.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Opaque envelope method with variable block size.
Masking / blinding
Blinded (masking used)
